An FET Mic from Groove Tubes

The Groove Tubes GT30 microphone is a true condenser, with the same capsule design and options as the GT44, except Groove Tubes uses a warm Class A FET circuitry that operates on standard +48v. It incorporates all of the features of the popular GT44 with FET circuitry replacing the tube for a great all around mid-sized diaphragm microphone at a modest price. Great on acoustic instruments and as drum overheads, the GT30 also shines on vocals. The GT30 includes hard mount and a hard mic case.
